果浆酶、果胶酶单一酶类的可酶解对象范围较窄，酶解效率不如由果胶酶、纤维素酶、蛋白酶、淀粉酶、木聚糖酶等成分组成的粥化酶高。粥化酶是由黑曲霉经过固态发酵而获得的复合酶,它以果胶酶、纤维素酶、木聚糖酶为主,并含有蛋白酶、淀粉酶等。在果蔬加工中,粥化酶可以溃碎果实，破碎植物细胞，使果蔬原料产生粥样软化，从而提高果蔬汁的出 汁率、澄清度以及降低果汁粘度。目前尚未有以粥化酶酶解罗汉果出汁制备罗汉果果汁的方法的报道。The enzymatic hydrolysis of single enzymes of fruit pulp enzyme and pectinase is narrow, and the enzymatic hydrolysis efficiency is not as high as that of pectinase, cellulase, protease, amylase and xylanase. The porridge enzyme is a complex enzyme obtained by solid state fermentation of Aspergillus niger. It is mainly composed of pectinase, cellulase and xylanase, and contains protease and amylase. In the processing of fruits and vegetables, the porridge enzyme can break the fruit, break the plant cells, and make the fruit and vegetable raw materials produce atherosclerosis, thereby increasing the juice yield, clarity and reducing the viscosity of the juice. At present, there is no report on the method for preparing Luo Han Guo juice by enzymatic hydrolysis of Luo Han Guo juice.
酶解的效率及时间主要受酶的活性影响，酶的活性越高，则所使用的酶解时间就更短，效率更高。此外，酶的活性受环境的温度、pH、压力所影响，调节环境的温度、pH、压力等因素将会使酶的活性提高或下降，从而影响酶解时间及酶解效率。The efficiency and time of enzymatic hydrolysis are mainly affected by the activity of the enzyme. The higher the activity of the enzyme, the shorter the enzymatic hydrolysis time and the higher the efficiency. In addition, the activity of the enzyme is affected by the temperature, pH and pressure of the environment. Adjusting the temperature, pH, pressure and other factors of the environment will increase or decrease the activity of the enzyme, thereby affecting the enzymatic hydrolysis time and the enzymatic hydrolysis efficiency.
超高压处理(μltra high pressμre，ΜHP)又称为高静压处理(high hydrostatic pressμre，HHP)，是指以水或其他液体作为传压介质，经100MPa以上压力处理，在常温甚至更低的温度下达到杀菌、灭酶和改善食品功能特性等作用的新型技术。因此，常规的超高压处理不仅将抑制酶的活性，不利于酶解反应。文献《超高压处理对鲜橙汁中果胶酶及过氧化物酶活性的影响》(陈贺庆等，食品科学[J]，2011(15):54-57)公开了果胶酶在室温15℃，压力200MPa的超高压环境处理10min后，酶活性较常压提高1％～2％，而压力≥300MPa时，酶活性下降30％左右。因此，在一定处理时间下，若以压力为横坐标，酶的活性为纵坐标描绘活性曲线，存在着一个伴随压力不断增大而酶的活性先提高后下降的峰形区域(以下简称“活化区”)。因此，以一定超高压条件处理酶类，可使酶类达到一定程度的活化效果。然而，酶具有高度的生物特异性，不同酶类的活化区有可能重叠，也有可能不重叠，某些酶类甚至不存在所述的活化区。Ultrahigh pressure ((HP), also known as high hydrostatic press μre (HHP), refers to the use of water or other liquid as a pressure transmission medium, treated with pressure above 100MPa, at room temperature or even lower temperature A new technology that achieves the functions of sterilization, enzyme elimination and improvement of food functional properties. Therefore, the conventional ultrahigh pressure treatment will not only inhibit the activity of the enzyme, but also be detrimental to the enzymatic reaction. The literature "Effect of ultra-high pressure treatment on pectinase and peroxidase activity in fresh orange juice" (Chen Heqing et al., Food Science [J], 2011 (15): 54-57) discloses pectinase at room temperature 15 ° C, After treatment with an ultra-high pressure environment of 200 MPa for 10 min, the enzyme activity increased by 1% to 2% compared with normal pressure, while when the pressure was ≥300 MPa, the enzyme activity decreased by about 30%. Therefore, under a certain processing time, if the pressure is the abscissa, the activity of the enzyme is the activity curve of the ordinate, and there is a peak-shaped region where the activity of the enzyme increases first and then decreases with the pressure increasing (hereinafter referred to as "activation". Area"). Therefore, treatment of enzymes under certain ultra-high pressure conditions can achieve a certain degree of activation of the enzymes. However, enzymes are highly biospecific, and the activation regions of different enzymes may overlap or may not overlap, and some enzymes may not even exist in the activation region.
目前尚未有超高压处理活化粥化酶的公开报道，也没有超高压处理联合粥化酶制备罗汉果果汁的公开报道。At present, there is no public report on the activation of porridge enzyme by ultra-high pressure treatment, and there is no public report on the preparation of Luo Han Guo juice by ultra-high pressure treatment combined with porridge enzyme.
温度作为影响酶类活性的核心因素之一，为了达到最大的酶解效率，使酶解环境处于最佳温度是实现最大酶解效率的前提。对于粥化酶而言，酶活性最高的适宜温度是45℃；但对于罗汉果而言，45℃的温度造成了一部分营养及风味成分的损失，最终影响成品的口感。Temperature is one of the core factors affecting the activity of enzymes. In order to achieve the maximum enzymatic efficiency, it is the premise to achieve the maximum enzymatic efficiency in order to optimize the enzymatic hydrolysis environment. For porridge enzymes, the optimum temperature for enzyme activity is 45 ° C; but for Luo Han Guo, the temperature of 45 ° C causes a loss of some nutrients and flavor components, which ultimately affects the taste of the finished product.

由表6所示可知，与对比例9、10比较，本发明实施例1～6所得罗汉果果汁的蔗糖、果糖、葡萄糖等含量明显降低。说明本发明采用酵母处理果汁，能降低果汁中糖分及热量。As shown in Table 6, the contents of sucrose, fructose, glucose and the like of the mogroside fruit juice obtained in Examples 1 to 6 of the present invention were significantly lower than those of Comparative Examples 9 and 10. It is indicated that the present invention uses yeast to treat juice, which can reduce the sugar and heat in the juice.
6.产品口感比较6. Product taste comparison
取实施例3得到的罗汉果果汁a～h,分别测定口感。The mogroside fruits a to h obtained in Example 3 were each measured for texture.
每名受试者依次给予实施例1得到的罗汉果果汁a～h作为受试品食用，总量10ml，在10min内分2～3次食用完毕。每样受试品食用完毕后需等待15min，等待时间结束后继续食用下一受试品。实验开始前及等待期间，以纯净水及无机盐饼干清理受试者的味觉。从特征气味、特征口味、甜味、苦味、涩味、特征余味等方面评价各受试品的口感。各项指标，0分为最小感受值，6分为最高感受值；各项结果以平均分表示。Each of the subjects was sequentially administered with the mogroside fruits a to h obtained in Example 1 as a test article, and the total amount was 10 ml, which was completed in 2 to 3 times in 10 minutes. Wait for 15 minutes after each test article is consumed, and continue to consume the next test after the waiting time. Before the start of the experiment and during the waiting period, the taste of the subject was cleaned with pure water and inorganic salt biscuits. The taste of each test article was evaluated from the aspects of characteristic odor, characteristic taste, sweet taste, bitterness, astringency, characteristic aftertaste and the like. For each indicator, 0 is divided into the minimum perceived value, and 6 is divided into the highest perceived value; each result is expressed as an average score.

由表7所示可知，罗汉果汁a～c的口感差异不大，有较明显的甜味，但仍然有突出的特征气味、口味、余味以及苦涩味，从而影响整体口感。酵母处理后的罗汉果汁d，除甜度外的各项口感评分都降低，但对甜味影响不大，仍然能感受到明显的甜味。以上结果表明，采用酵母处理罗汉果果汁后，对甜味等愉悦型口感影响不大，但能明显祛除特征气味、口味、余味以及苦涩味等厌恶型口感。As can be seen from Table 7, the taste of the Luohan juice a to c is not much different, and there is a distinct sweetness, but there are still outstanding characteristic odors, tastes, aftertastes and bitterness, which affect the overall taste. After the yeast treatment, the Luohan juice d, the taste scores except the sweetness are reduced, but the sweet taste is not affected, and the sweet taste can still be felt. The above results show that the use of yeast to treat the Luo Han Guo juice has little effect on the pleasant taste such as sweetness, but it can obviously eliminate the aversive taste such as characteristic smell, taste, aftertaste and bitterness.
